I was/am in that position and bought a Wave for a few reasons.
- It fits in my garage
- It is simple and easy to get started but seems like more skilled people like it in high winds, so it doesn't take you to a complete dead end as you get better
- I have to trailer, so quick setup solo lets me get some evening sailing time.
- It is easy to sail alone and can be righted by one person easily (so I read) yet it also sails respectably with two.
Alternatives I considered were a bigger Hobie or a Flying Scot, but they presented challenges for storage, setup, and confidence for use solo. Remeber that I am completely new to this, so could be completely wrong!
My wife and I took three 1 hour lessons on a Wave and I read a lot, and so far we've been doing fine, with no regrets about getting the boat.
All that said, it's not perfect. I already wish we had a jib so I felt more like a real sailor, but I know the Wave jib is not much use. I wish I could have found a good used one, but there are not many, so I had to pay for a new one. People keep wanting to come out with me and it is kinda fun to do that, but the boat is a bit small for a crowd and they slow it down.
A Getaway may have solved these problems (except the cost), so that's something to think about if you have the room, are not trailering, and are likely to be sailing with others most of the time.
